Make Ahead and Storage Tips
You can prepare the pastry cream up to 2 days in advance and store it covered in the refrigerator.
Store the assembled cake in the refrigerator for up to 3 days. Bring to room temperature for about 20 minutes before serving for best texture. Freezing is not recommended once assembled due to the custard layer.
How to Serve It Beautifully
Serve on a simple white cake stand to highlight the glossy chocolate top. Add a small swirl of whipped cream or a cherry on top for a classic touch.
Creative Leftover Ideas
Cube leftover cake and layer it into parfait glasses with extra whipped cream.
Turn slices into mini trifles with fresh berries.
Serve small pieces alongside coffee for an elegant afternoon treat.
Extra Tips for Success
Always use freshly grated chocolate for smooth ganache.
Slice with a warm knife for clean edges.
Let the cake rest before serving to enhance flavor.
Make It a Showstopper
For a polished look, let the ganache gently drip over the edges. Keep the top smooth and glossy. A single cherry or swirl of chocolate cream in the center makes it feel bakery worthy without extra effort.
Variations to Try
Add a thin layer of sliced strawberries with the pastry cream.
Use dark chocolate for a more intense topping.
Infuse the pastry cream with a hint of espresso for depth.
